From the WSJ news alert thingy:

Whole Foods’ founder and CEO John Mackey posted many messages on Yahoo’s stock forums for about eight years, ending around August 2006, the company confirmed Wednesday. Mr. Mackey used the pseudonym “Rahodeb,” an anagram for Deborah, the name of Mr. Mackey’s wife. On the boards, Rahodeb routinely cheered Whole Foods’ financial results, trumpeted personal gains on the stock, and bashed rival Wild Oats.

hahahahahaha DOH
